COMBINED CULTIVATOR ND HARROW.

'SPECIFICATION forming part of Letters Patent No. 682,720, datedSeptember 17, 1901. V Application filed October 8, 1900. VSerial No.32,419. (No model.) l

*the object of the invention is to provide means whereby thetooth-carrying beams are under dium of the handle-bars and may beinstantly expanded or contracted in width.

l accomplish the objects of the invention by the mechanism illustratedin the accomo panying drawings, in Whichthe control of the operatorthrough the me- Figure 1 is a perspective view of my invention, and Fig.2 a plan view of same.'

Like letters of reference indicate like parts throughout both views ofthe drawings.

A is a central longitudinal beam, to each side of which arelaterally-adjustable wings lcomprising the beams B and C. The beams j Band C are hinged separately at their front ends to the beam A in themanner as shown '3o and are held in prescribed distances of each 'other`by the bars of strap-iron D, which bars Aare pivotally secured by boltsd at each end of the bar D, said bar being thereby bolted to each of twoadjacent beams. The beams A', B, and C have the harrowteeth, as shown.or may be -of langle-iron or steel. A will preferably have the wheel aat its for- `ward end to -keep that end from going too deep into thesoil and for convenience in turning "the cultivator at the ends of therows and for transporting it from iield to field. The beam A will alsohave attached near its rear end the traction-bar E. This attachment willbe a iieXible one to permit the front end of the bar to be varied inaltitude, and this altitude will be maintained by the standard E',having a series of holes e, through which the loop supporting the barwill be fixed at various heights. in width to afford a broader supportfor the handle-bar guides hereinafter to be described The rear of thebeam A is expanded i l l Said beams may be-of wood rIhe beaml and tosupport two rows of teeth: The side wings `formed by the beams B C B Care spread normally away from the central lon- 55 gitudinal beam A bythe spring F, consisting of a bar having a middle coil and ends caughtin eyebolts f f,psecured to the beams C C.

G G are the handle-bars, which are fastened to the respective outsidebeams B B. They 6c, are braced to their respective beams by the braces gg and are additionally held and guided by an inside brace for each ofpeculiar construction, comprising the diagonal member h, secured at itsupper end to the 65 l handle, and the horizontal curved member h', whichis fastened rigidly at its outer end to the outer beam B and isconnected at its inner end with the lower end lof the diagonal member h.The horizontal members of each 7o brace rest on top of the central beamA and on their respective intermediate beams. They rest onbearing-plates of metal e' and are held l down to the plates by theclips j, which, however, permit of sliding movement there- 7 5 ithrough. These horizontal members afford a broad and stable bearing forthe handles and serve also to keep the individual beams from jumping outof the plane common to all. I consider this brace construction as a veryim- 8o portant feature ot' my invention. More than two beams may be usedin making up .the Wings or only one may be used. This 'machine isspecially adapted to be drawn between rows of growing plants and is y85f instantly adjustable in width to suit the space between the rows bytheoperator, who, having lhis hand constantly on the handles G G, throwseither or both of the wings in or out by moving the handle attached tothe wing 9c t0 be moved. The action of the spring F being to spread thewings, the operator will be compelled to hold the handles against thistendency.

Iam aware thatimplements have been made 95 with .laterally adjustabletooth carrying beams and do not broadly claim such construction; but

What I do claim as new, and Wish to secure by Letters Patent of theUnited States, is roo l. The combination of the central longitudinalbeam, side beams hinged at their front ends to the central beam, andlaterally ad j ustable as to their rear ends, handles secured to theside beams whereby the lateral adjustment of said beams is made andheld, and resilient means for normally spreading the hinged members,substantially as described and shown.

2. The combination with two pairs of beams hinged at their forward endsso as to be laterally adjustable as to their rear ends, said rear endsof each pair of beams being connected by double-hinged bars, a spring topress the pairs of beams in opposite direction from each other andhandles secured to one of the beams of each pair of beams said handleshaving inside sliding braces, substantially as described and shown.

3. The combination of a central longitudinal beam, a pair of beams oneach side of said central beam each hinged to the latter at its forwardend to swing laterally, said side beams being connected in pairs bydoublel hinged bars, a spring to press the side pairs away from thecenter beam, handles secured to the outer ones of the side pairs ofbeams each ot' said handles having an inside brace with diagonal uppermember attached at its upper end to the handle and having a horizontalcurved base which rests on top of the center beam and its respectiveside beams and fastened to the handle-carrying beam and clips to holdthe curved base to the beams to permit of a sliding attachment ofthecurved base to the beam,all substantially as described and shown.

ln witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 6th day ot' October, A. D. 1900.
